The National Weather Service in Spokane issued a flood watch warning for Whitman County, according to the National Weather Service website. The warning is in effect from Tuesday evening until late Wednesday night. 

Residents in the county should expect heavy, persistent rain up to two inches by Wednesday night, according to the warning. The rain will cause all water sources in the region to rise, including streams, creeks and rivers. This may lead to minor flooding in surrounding areas.

Residents should clear major water drains and check culverts to ensure that water can run freely, according to the warning. Residents should also monitor later weather forecasts in case of flooding.
